2.6.22 is awfully old in terms of kernel.org development.  Are you able
to determine whether more recent kernels have the same problem?

This could be dependent upon the devidce driver which is in use. 
Please provide details about the physical layer?

Re: [Bug 10739] 8139too carrier state problem, was: PPPoE not working...

[Jarek Poplawski]

Hi,

I forward this subject to netdev list. IMHO modprobe shouldn't be
needed to get this driver RUNNING after plugging the wire. (I've tried
a similar card with 2.6.24 kernel and ifconfig eth0 up was enough).

If there is no good advice I think it would be better to close the
current report and reopen it with better title.

Regards,
Jarek P.
